ALBERT FRoDh, OF BAUTZEN, GERMANY. MO' tiOR-VEHICLE.

To all whom it may concern}:

Be it known that I, ALBEnTFRtSDE, manux facturer, a subject of the King of Saxony, and a resident of 10 Fischerpforte, in Bautzen, in

the Kingdom of Saxony, German Empire, have invented certain new and useful Improvements in Motor-Vehiclesfor Agricultural Purposes, of which the following is a specification.

'. This invention concerns a motor-vehicle for agricultural purposes-that is to say, an agricultural universal automobile which may be used as a motor in performin agricultural labors and as such satisfies in t e most erfect manner all the demands that coul be made on it.

The new motor-vehicles can be made to serve as an agricultural automobile for plowing, harrowing, sowin mowing, sheaving, grasscutting, hay-ma g, and so on; urther, as an engine or locomobile for threshing, chaff-cutting, churning, pumping, generating electric light, and so on; further, for drawing harvesting-cars and soon, also for watering gardens and fields and for extinguishing fires.

An important point with this inventionis that the motor or the engine of the-motor-vehicle is so arran ed that it can be shifted lat- 3'6' eral y in sue a manner a one-s1 e o e motor-car may be more or less loaded. This arrangement is of great value, for the reason that by means of the same ifthe motor-vehicle or the hind part of it, which carries the motor, is connected with an agricultural implement-mowing-machine, plowing-machine, sowing ap aratus, or the likethis working side of the motor may by a corresponding shiftin be loaded so muchmore that the efficiency 0% the respective agricultural implement or machine is increased by the higher pressure exerted upon it. Diminishing the load is, on the other hand, necessary when a machine is connected with the motor, which requires less driving-powerfor instance, a mowin -machine and the like. In consequence of t e shiftableness of the motor there is, moreover, attained the advantage that the motor-vehicle may beproportionately light, and can therefore be used also for working soft soil. It is further possible to compensate or balance the load so that with a one-sidedloadingthelessloadedsidedoesnot run in advance of the other and that thus the vehicle isable to move forward in a straight line. The possibility of shifting the 'ce all Specificatign of Letters latent. i umiou 5164' Apr-1x19. 1904. sum No- 203,959. '1.

of gravity 'has,further, the great advantage that the motor-vehicle which forms the subject of this invention can move about and.

work on slanting .soil or inclined surfaces,

.which it is rather frequently requiredto do.

The-inventionfinally offers several other advantages profitable to a riculture, but which may not be mentionediiere in support of the patentability of the invention, as they are less essential.

This motor-vehicle may of course be of many different forms of construction, and it would lead too far to enter into all the details here. The leading principle of all these constructions would be the displacing of the center of gravity-mother words, the shift- 'abl eness o the motor-sothat for describing the invention the form of construction shown on the accompanying drawings may be used without limiting thereby in any way the variations which would naturally be covered by the patent applied for.

On the accompanying drawings the invention is illustrated in Figure 1 in a side view; Fig. 2,in a back view; ig. 3, in a plan or top view.

Similar characters refer to similar parts throughout the several views.

The shiftableness of the motor and its arrangement on the vehicle is as follows: On the supports 1 and 2, resting on the springs 8, there are provided two bearings 15 and 16, in which are guided the two bars 18 and 19, one of which, 18, is provided in the middle with'a thread 17. B means of the same and a nut provided on t e motor, which nut engages the said thread, the motor 20 can be adjusted by turning the hand-wheel 21 on the right of the seat 7 of the driver. The transmission of the motion from the hand-wheel 21 to the motor 210'isefiected by a chain-wheel 22, attached to the; hand-wheel 21, over which cliain wheel rii nsa chain 24,'which after passing over two uide-pulleys 23 runs over another chain-w eel 25, which is so' connected with the toothed wheelwork 26 that the same may be rotated with the bar 18 in one direction or the other. This transmission may also be effected in another and more simple 7 over the toothedwheel on the rack 18. With this arrangement the mechanism whichtransmits the power from the driving-shaft of the motor 20 to the driving-shaft of the automo- IIO bile may either be shiftable directly with the be shifted. It is in idl connected to the motor 20. U on this co ar wheels 27 are ke ed for the 'fferent speeds of the automob' e. If now the driving-shaft 28 is rotated by the motor, the transmission is effected by a toothed wheel 29 on the driving-shaft 28 gearing with a toothed wheel 32 throu h the toothed wheels 30 and 31. This whee 32 is arranged on a shaft 33, rovided with a toothed wheel 34, with whic the toothed wheels 35 36 37 38 may be made to ear. If this is done by means of the hand es provided for this purpose and if one of the toothed wheels 35 36 37 38 is made to gear with the toothed wheel 34 and one of the wheels 27, the connection between and transmission of power from the motor 20 to the. drivin -shaft 12 is established, and the automobi e can, according to the speed for which it is adjusted, drive faster or slower.

The construction and arrangement of the levers for adjusting the speed is as follows: On the front wall of the motor is arranged a late 41 with slits, through which pass the and-levers 40. -The latter are rovided with catches in suitable places at t e lower edge which engage with the plate 41 when the lever is pressed hack contrary to the tension of the springs 42. These springs 42 rest with one end against the plate 41, with the other against regulating-rings 43 on the levers 40. If, therefore, a lever is raised, the respective toothed wheel 35 36 37 38 is set to gear with the corresponding toothed wheel 27 and at the same time with the longtoothed wheel 34. The retrograde motion of the motor is effected by the toothed wheel 30 being thrown out of ear with the toothed wheel 29, for the toothe wheel 30 is j ournaled with the toothed wheel 31 in a shear 44, capable of pendulatin around a shaft 33 of the two toothed whee s 32 and 34. This shear carries the disengaging lever 45, which, like the levers 40, has its handle near the seat 7 and has also at its lower edge two catches, with which in its end positions it can be hooked into the plate 41. On the shear 44 is provided another toothed wheel 46, which, the same as the toothed wheel 31, is in constant gear with the toothed wheel 32. If now the lever 45-is moved out of the position shown in Fig. 1, the toothed wheels 30 and 29 are thrown out of gear, while the toothed wheel 46 is set to gear with the toothed wheel 29. In consequence of this the transmission of ower from the motor-shaft to the drivinga e is effected with one wheel less than before, as a result of which the automobile is moved backward. On the driving-axle 12 of the automobile there are further arranged two clutch-couplings, by means of which the two large hind wheels 11 may be disconnected if the automobile is to supply power while standing still. The construction of this mechamsm is such that there are arranged on the axle 12 two halves of clutch-couplin s 48, which are keyed onto it by means of sliding wedges 47 and can be shifted in an axial direction. ling halves are the clutches 49 of the cou ling-halves affixed to the naves of the wheeis 11, so that through the coupling 48 49 the axle 12 may be connected with the wheels 11. The throwing into and out of gear of the two coupling-halves is effected by means of two hand-levers 50, which stand out at the two sides of the seat 7 and whose two lower ends 51 move the angle-levers 53 through the drawing-rods 52, whose other arms 54 catch around the clutch-coupling halves 48 by means of forks. The angle-levers 53 54 are fastened to the supports or parts 1 and 2 of the frame by means of the little trestles 55.

If the two hind wheels are-disconnected in order to use the automobile as a stationary engine, on the prolonged ends 14 of the axle 12 a belt-pulley maybe afiixed, by which the power of the motor may be transmitted to another machine.

At the side of the seat 7 there is, further, the hand-lever 56, which serves as a brake through the arrangement that the other end of the same, 57, works a lever 59 on the shaft 60 through the drawing-rods 58, whose ends carry the working levers for the bands of the brake placed around the naves of the wheels.

If, for instance, the automobile is to be used as a fire-engine or as a squirt or watersprinkler, the following squirtin device may be applied: The bar 19, whic serves to drive and carry the motor, may at the same time be used for connecting the motor with a pump 62. Opposite to the plunger-piston 63 is arrangedin that case on the bar 19the eccentric 64, which works the lunger-piston through the short bar 65. ter a special toothed wheel has been ut upon the end 66 of the motor-shaft 28, wiiich extends to both sides of the motor, the pump may be started by this special toothed wheel en aging the toothed wheel 69 on the bar 19. T e toothed wheel 69 is connected with the latter through a sliding wedge in the groove 67 of the bar 19, so that at every position of the motor to the middle plane of the driver the pump 62 may be set to work. This pump sucks up the liquid through the socket 68 and drives it through the air-chamber 70 to the dischargesocket 71. The automobile,

which, as already said, is

Opposite to these clutch-coup- ["in agricultural universal automobile and has, therefore, the most variegated labors to perform, draws or carries the devices or apparatus required for this. The simplest mode to attain this, .where there is merely a question of drawing or driving, is to arrange two hooks on the axle. To this can be attached a lar erake or harrow, and so on, and on the road harvesting-cars and so on may be hung on. With another mode of fastening a cross-beam of a suitable shape is screwed oint the divided axle-boxes orinto the clamps arranged on these, to which the respective implement may be attached. A further mode of fastenin is the following: To the clamps g, arrange in front and behind, is affixed a frame which is placed around the whole wheel and is fastened on the other side upon the prolonged piece 14 of the axle 12. This frame is then supported all around at the points 72 and 73 and 74 and 75, 76, 77, and 78, Fi 1. At the points 75 and 77 the frame is astened by screws. The frame might also be interrupted from 72 to 79 and go from there to 80, 81, 82, 83, and 84, and then to 72, (on the other side.) It may be arranged vertically or horizontally. To such a device it is easy to hang or attach a plow, a harrow, and so on. A harrow, roller, and so on may also be hung or attached to a hook fastened to the frame. On the parts 74 73 and 73 75 a sowing-box or the like may be put and eventually be supported by two guiding-rollers. In short, t ere is a variety of ways in which an agricultural implement may be attached. By means of this device a plow, harrow, potato-drill, and so on may also easily be hung on in such a manner that the object of the shiftableness of the motor will be close to the axle of the hind wheel. In this Way the plow, harrow, and so on will be brought nearer the point u on or over whichthe pressure is to be direct y exerted.

The shiftableness of the motor may of course be attained in another way than the above described. As already stated, it is also possible to shift the motor still farther sidewise while retaining the same arrangement allowing of fixing the mechanism of the transmission and so on inde endently of the motor.that is to say, ri i ly or immovably. The description of t is arrangement is as follows Between the two bars 18 and 19 and on a level with the same is a third bar which forms a long-toothed wheel. With this lon -toothed wheel is connected the motor-sha t 28, and this is able to drive the long-toothed wheel and, in combination with a pair of transmission-wheels 35, 36, 37, or 38 and 27, the axle 12, and thereby also the automobile. The whole mechanism for the transmission and for altering the s eed is, however, arran ed rigidly and is p aced in the middle of t e automobile. It is on the whole similar to the above-described mechanism, only the plate 511, through whose slits pass the levers for altering the speed, is fixed independently of the motor. This plate is therefore no longer on the motor, but may be arranged anywhere else. The mechanism for the retrograde movement may likewise be rigidly fixed, when of course it requires to be arranged under the long-toothed wheel for the variations of s eed. t may of course be near the top of t e motor; but it must then follow the movements of the same. It is therefore advisable to arrange this single lever where the ma'orit of the others are if the same are not s able The connection of the motor-shaft with the fire-en ine ma with this arrangement be established through the long-toothed wheel. The last-described arrangement for the shiftableness of the motor has in so far a great advantage, as the motor may now be shifted sidewise up to the springs 8, whereby the advantage aimed at b the shiftableness of the motor is considera ly increased As to the differential mechanism, which as a rule is on-the left of the axle-box on the left side of the automobile, the same may with the last-described arran -ement of the construction for the shiftab eness of the motor most advantageously be placed inside'that is to say, beneath the wheels 27.

What I claim as my invention, and desire to secure by United States Letters Patent, 1s

A motor-vehicle for agricultural purposes, in which the motor 20 is arranged on two cross-bars 18 and 19 on which it can be shifted and of which one is provided with a screwthread 17 in a manner that the lateral shifting of the motor 20 may be effected from the seat 7 of the driver by means of suitable transmission devices, substantially as set forth.

In witness whereof I have. hereunto signed my name, this 26th day of March, 1904, in the presence of two subscribing witnesses.
